Throughout the weekend, athletes and spectators will be able to enjoy the award winning gardens and a fun-packed festival village featuring live music, shopping, food and drink, children’s entertainment, yoga and more.
Our family friendly multisport event weekend in Kent features triathlon, duathlon, aquabike, aquathlon, swim and run races for all ages and abilities. You can also race with team of friends in one of our relays options!
